Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed September 10, 1908. Serial No. 452,-187.

To all whom it may concern:

Be it known that we, WILLIAM MOGRA'IH and EDWARD JonN BUGKBEE, citizens of the lh1itedStates, residing at Urbana, in the county of Champaign and State of Illino s, have invented certain new and useful Improvements in Pipe-Couplings; and we do declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to coupling devices larly to the couplings used in connection therewith. v

The object of the invention is to provide a coupling which may be readily and conveniently connected, and which will form a perfectly air-tight joint between two pipe sections, and at the same time permit rotary movement of either section with respect to the other.

A further object of theinvention is to utilize a coupling of this type to connect the air systems of two different cars which have relative movement.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arran ement of parts, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a detail side elevation of the coupling used to connect two cars, Fig. 2 is a top lan View thereof, and Fig. 3 is a longitu inal sectional view of one of the couplings.

Referring more especially to the drawings each coupling comprises a socket member 1, which is provided with a threadedfineck extension 2, and a socket or seat 3, in which the head 4 of the -pipe section 5, is seated. This head 4 is screwed on the end of a pipe and is preferably provided with. a packing.

ring 6. It is recessed at 7 to form an annular flange 8, adapted to enter a packing channel 9, formed in the coupling member 10, which preferably isformed in the shape' of an elbow. In assembling each coupling the headt of the pipe section 5 is seated in the socket 3, and the pipe section 5 projected through an aperture ll formed in the coupling member 1. The flange 8 is engaged in the packing channel 9 and the threaded collar 2 engages similar threads. within the socket 9,, so as to .clamp the members 1 and 10, to etherwith the pipe section 5, and its head located intermediate the two and thereby making a perfectly air tight coupling.

In applying this coupling to connect different cars of a train seven couplings are employed to accomplish the connection although only one of the number may be unjointed when 'the cars are disconnected. Two of the seven couplings are secured to the car and are designated as couplings A and A, having secured to them the connecting pilpe links 12, at the lower end of which are 0- cated the couplings B and B, which in turn have secured to their elbow ends the cou lings C and C. These couplings C and (J' are connected to pipe links 13, which communicate with pipe links 14 by elbows 15.

The lower ends of the links 14 are connected cooperating coup ings B and B permit the swinging of the sections when the cars come together. Any lateral motion of'the cars is taken up by the coupling C. It will be readily seen that an eflicient and flexible connection between two cars is provided, and this without resorting to the use of flexible tubes, which cannot possibly stand the strain exerted upon them and have any length of life.

From the foregoing description, taken in connection with the accompanyin drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claim.

Having thus described -our invention, what we claim and desire to secure by Letters Patent is In a device of the class described, the combination with a pair of pipes, elbows on their ends, flexible coupling on their ends arranged at horizontal right angles to the pipes, depending connecting pipe links secured to cured to the 1pc links and exten g horiset our hands in presence of twosubscribing wltnesses.
